Saxonmeyer, Park Forest, Ill.,assignor to Whiting Corporation, a corporation of Illinois Filed Feb.24, 1964, Ser. No. 346,649 9 Claims. (Cl. 104-249) This inventionrelates to devices for holding one or more railway cars on a section oftrack, and more particularly to a new and improved car holder assemblyof the type adapted to be mounted between rails of a track forengagement with the axle of a car to act as a stop against movement ofthe car in one direction and to permit movement of the car in anopposite direction.

A car holder of the type mentioned above is fixedly mounted betweenrails of track in a siding or yard, for example. The car holder isprovided with collapsible means which include a member which is engagedby a railway car axle when the collapsible means is erected and which iscleared by a railway car axle when the collapsible means is collapsed.The collapsible means are designed so as to support the axle engagingmember in a manner to act as a stop against movement of a car in onedirection and to permit movement of a car in an opposite direction.

In practice, this type of car holder is mounted between rails of tracksection having a slight grade. A railway car is switched onto thisgraded track section and allowed to travel along the same until itcontacts the car holder thereby coming to a sudden stop. Another car isthen switched onto this track section and allowed to couple with thefirst car which is held by the car holder. Additional cars are switchedonto the track section until the desired number of cars are coupledtogether. It will be realized that the car holder engaging the first carswitched on the track section acts to hold all of the other cars coupledwith this first car. When it is desired to remove these cars from thesection of track, a switch engine or the like is coupled with the lastcar on the graded track section and then operated to pull the cars upthis track section onto another section or length of track.

It Will be realized that the coupling of these cars with each other andwith a switch engine or the like produces coupling shocks ofconsiderable magnitude which are transferred to the car holder throughthe car axle which is engaged by the car holder. If these couplingshocks are excessive, damage may result to the car holder or to therailway car axle or both.

Accordingly, it is a primary object of the present invention to providea new and improved railway car holder assembly which has the ability toabsorb coupling shocks so as to prevent damage to the car holder and tothe railway car truck assembly having the axle which is engaged by thecar holder.

Another object of the present invention is the provision of a railwaycar holder having an axle engaging member supported by new and improvedcollapsible means so as to adapt the car holder for acting as a stopagainst movement of the car in one direction thereof and for permittingmovement of the car in an opposite direction.

A further object of the present invention is the provision of a new andimproved railway car holder assembly which is adapted to absorbconsiderable coupling shocks and which minimizes the possibility ofderailment of the railway car truck assembly having the axle engaged bythe car holder.

A still further object of the present invention is the provision of anew and improved railway car holder assembly which is adapted to absorbconsiderable coupling shocks thereby substantially reducing thepossibility of failure of the railway car axle engaged by the carholder,

and which is adapted to engage the car axle in a manner tending furtherto reduce the likelihood of axle failure.

These and other objects and advantages of the invention will becomeapparent from the following specification disclosing a preferredembodiment of the invention which is illustrated in the accompanyingdrawings.

Briefiy and by way of introduction, the railway car holder assemblyincludes a pair of side-by-side car holders mounted between rails of atrack section in parallel relation with the latter. The car holders aremounted by separate track means for movement in either direction along arectilinear path which is parallel to the direction of car movement onthe track section. Each car holder includes a railway car axle engagingmember supported by collapsed means forming a part of the car holder.Both car holders are fastened to a cross link member which is connectedwith a cushioning device anchored between the rails of track in spacedrelation with the car holders. The cushioning device serves toresiliently mount the car holders to allow the latter to yield as theyare struck by a car axle thereby adapting the assembly to absorbcoupling shocks so as to minimize substantially the possibility ofdamage to the car holders and/ or to the railway car axle contactedthereby.

Referring now to the drawings, the railway car holder assembly of thisinvention includes a pair of car holders, generally designated 10 (FIGS.5-7), mounted side-byside between rails of a track section and extendinglongitudinally of the latter. As both car holders are of identicalconstruction, only one car holder 10 is illustrated and described.

Car holder 10, which is of the type of device often referred to as arabbit, includes a pair of parallel beams 12 and 14 which are securedtogether in spaced relation by a pair of elongated blocks 15 and 16sandwiched between the beams adjacent the ends of the latter. The beamsmay be secured to the blocks by any suitable means, as by welding, forexample. The end of the car holder including block 15 may be termed theforward end of the car holder. Block 15 has an upwardly and forwardlyinclined surface 15a, and a transversely extend ing opening 17 snuglysupporting a shaft 18, which shaft has reduced in diameter end portions18a supporting respectively a pair of rollers 19 by means of rollerbearing assemblies 20 (FIG. 8). Roller bearing assembly 20, whichengages shaft portion 18a and inner cylindrical surface 19a of theroller, is held between an annular shoulder 18b on the shaft and aretaining ring 21 which is held in an annular groove 19b opening intosurface 19a of the roller. Nuts 22 threadingly engageable with oppositeends of shaft 18 engage rings 21 for retaining rollers 19 on the shaft.

A block 16 at the opposite or rear end of the car holder mounts a pairof rollers 23. The mounting for these rollers is identical to theconstruction for mounting rollers 19, and, therefore, will not bedescribed again. Block 16 includes an upwardly and rearwardly inclinedface 16a as best seen in FIGS. 5 and 6.

An arm 25 comprising identical spaced plates 25a. and 25b has one endthereof pivotally mounted on a pin 26 which has opposite ends thereofsecured in suitable apertures in beams 12 and 14 intermediate thelengths of the latter. Plates 25a and 25b are secured together in spacedrelation by means of a spacer bar 27. A roller 28 is rotatably mountedon a pin 29 by means of a bushing 30, which pin has its opposite endssecured in openings in the corresponding ends of plates 25a, 25b remotefrom pivot 26. As will be explained hereinbelow, roller 28 is adapted toengage a railway car axle.

Plates 25a, 25b have short extensions at their lower ends supporting apin 31 which in turn supports a clevis member 32. A rod 34 has one endthereof threadingly secured to the bight portion of clevis 32. The otherend of rod 34 is freely slidable through an opening in a member 35 whichis fixed between beams 12 and 14 of the car holder. A nut 36 isthreadingly engaged on the end of the rod 34 adjacent clevis 32. Aspring 37 encircles a portion of rod 34 and has its opposite ends inengagement with nut 36 and member 35 for constantly urging arm 25 in aclockwise direction as seen in FIGS. 5 and 6. Rod 34 swings through alimited are during swinging of arm 25, and for this reason the openingin member 35 is slightly oversized to accommodate swinging movement ofrod 34.

A brace 40 has one end thereof pivotally mounted on a pin 41, which pinhas opposite ends thereof secured in suitable openings in arm plates25a, 25b. Brace 40 has a planar undersurface 40a adapted for rollingengagement on a roller 42 rotatably mounted on a pin 43 having oppositeends thereof secured in suitable apertures in beams 12 and 14. As willbe apparent from FIGS. 5 and 6, roller 42 supports the free end of brace40 during movement of arm 25 between its vertical position illustratedin FIG. 5 and its horizontal position illustrated in FIG. 6.

A stop pad 45 is secured to inclined face 16a of rear block 16. The freeend of brace 40 is adapted to abut stop 45 as arm 25 is swung upwardlyunder the influence of spring 37 thereby to limit swinging movement ofarm 25 in a clockwise position (as seen in FIGS. 5 and 6) and tocooperate with spring 37 for holding the arm in its vertical position.

As 'best seen in FIGS. 5-7, forward block 15 has a forwardly extendingprojection 15b provided with a transversely extending opening 47. A bentplate 48 is secured to block 15 beneath projection 15a by means offasteners 49, which plate supports by beans of fasteners 50 a magnet 51.

In like manner, rear block 16 has a rearwardly extending projection 16bhaving a transversely extending opening 53 therein. A bent plate 54 issecured to block 16 beneath projection 16b by means of fasteners 55. Amagnet 56 is secured to the underside of plate 55 by fasteners 57. Thepurpose of the magnets 51, 56 carried by car holder 10 will be referredto hereinbelow.

Foot operated releasable means are provided for holding arm 25 and brace40 in substantially horizontal or collapsed disposition as illustratedin FIG. 6. This releasable means includes a bent bracket 60 having asleeve 61 secured thereto, which sleeve rotatably receives a pin 62having opposite ends thereof secured in suitable bores in beams 12 and14. A spring 63 is received in a blind bore provided in block 15 andopening in face 150: thereof, which spring engages bracket 60 therebyconstantly urging the latter to swing in a clockwise direction (FIGS. 5and 6) about pin 62. Swinging movement of bracket 60 in this directionis limited by engagement of a foot portion 60a thereof with the uppersurface of an elongated plate 65 which is secured to the undersides ofbeams 12 and 14 along substantially the entire length of the latter. Afoot plate 67 is secured to the upper end of bracket 60 as by welding,which plate 67 includes a notch 68 at one end thereof (FIG. 7). Notch 68defines ear portions 680 and 68b. Notch 68 is adapted to receive roller28 and ears 68a, 68b are adapted to engage respective projections 69aand 69b (FIG. 9) formed on the free end of arm plates 25a, 25b forholding the arm in the position illustrated in FIG. 6, i.e. thecollapsed position. It will be apparent that the foot operatedreleasable means automatically engages the projections on the arm duringlowering of the latter, as smooth curved surfaces 70 on the arm plateengage the ends of ears 68a, 68b thereby swinging plate 67 in acounterclockwise direction (FIGS. 5 and 6) about pin 62 until the earsare allowed to snap over projections 69a, 69b on the arm. Stepping onplate 67 causes the same and bracket 60 to swing about pin 62 therebyreleasing arm 25 so that the latter may be erected under the influenceof spring 37.

As mentioned above, car holders 10 are mounted between rails of track inparallel relation with the latter for movement in either direction alonga rectilinear path parallel to the direction of car movement on thetrack rails. Referring now to FIGS. 2 and 8, a trackway consisting ofparallel, spaced channels 74 and 75 is mounted on railway ties 76 whichsupport the rails of a track section, the inside head surface of one ofthe rails being indicated by line 77 in FIG. 2. It will be understoodthat the entire railway car holder assembly is symmetrical about railwaytrack center line 78 shown in FIGS. 1 and 2. Channels 74 and 75 aresecured on alternate ties 76 by means of angles 79 which are secured tothe channels and mounted on the ties by means of suitable fasteners 80.Channels 74 and 75 are secured to the other ties by means of bars 82fastened to the ties by means of fasteners 83', the bar being secured tothe channels as by welding, for example.

As best seen in FIG. 8, the rollers of the car holder are confinedbetween the channels 74 and 75, the rollers being adapted to roll on theupper surfaces of the lower flanges of the channels. Channels 74 and 75are substantially greater in length than the length of the car holder topermit rolling movement of the latter along the channels. In theembodiment of the invention shown for purposes of illustration whereinthe car holder has an over-all length of almost 8 feet, the channelshave a length permitting a 6 /2-foot stroke for the car holder. As willbecome apparent below, the side-by-side mounted car holders areconnected with cushioning means for cushioning coupling shocks receivedby the car holders.

A clevis 85 (FIGS. 2 and 4) is secured to block 15 of the car holder bymeans of a pin 86 which is received in aperture 47 of projection 15b. Arod 87 has one end thereof secured to clevis 85 and the other endthereof se cured to a clevis 88 (FIG. 1) Clevis 88 is pivotally securedto one end of a cross link or equalizer bar 90 by means of a pin 91.Cross link 90 is pivotally secured at its midpoint between a pair ofspaced cross arms 92 at the midpoints of the latter by means of a pin93.

A long travel cushioning mechanism is mounted between the rails of trackjust forwardly of the pair of side-by-side mounted car holders 10. Thecushioning mechanism includes a plurality of parallel, elongatedcushioning devices which extend longitudinally of the rails in laterallyspaced relation. In the embodiment of the invention shown for purposesof illustration, five cushioning devices are provided, each cushioningdevice being indicated generally by numeral 95. As all cushioningdevices are of identical construction, only one device will be describedin detail.

Now referring to FIGS. 1 and 3, cushioning device 95 includes a cylinderor tube 96 having one end thereof secured to a plate 97 which extendslaterally between the rails of track. Plate 97 is secured to ahorizontally disposed plate 98 which is mounted on a reinforced concretefooting 99 by means of a number of anchor bolts 100. The other end ofthe tube 96 is secured between the upper surface of a horizontallydisposed plate 102 and the undersurface of a horizontal portion of abent plate 103. Sleeve 96 may be secured to plates 102, 103 by suitablefasteners or by welding. Plate 102 is secured to a reinforced concretefooting 104 by means of sets of anchor bolts 105 and 106. Anchor bolts106 are also used to secure plates 102 and 103 together. A rod 103 isconcentrically disposed within tube 96 and has one end thereof freelyslidable in an aperture 109 formed in plate 97. The other end of rod108' is threaded and mounts a piston 110, the piston being held to rod108 by means of a nut 111. A coil spring 112 is retained within tube 96around rod 108, which spring has one end thereof abutting plate 97 andthe other end thereof abutting piston 110. Manifestly, spring 112restrains movement of rod 108 to the right as seen in FIGS. 1 and 3.

The ends of rods 108 extend between cross arm plates 92 and are securedto the latter by means of respective pins 114. It should be apparentthat cushioning devices 95 allow cushioned long travel movement of thecar ho1ders in a direction from left to right as seen in FIGS. 2 and 4so as to adapt the assembly to absorb coupling shocks.

In practice, the railway car holder assembly of this invention ismounted between rails of a track section having a slight grade or slope,this slope being upwardly and to the left with reference to FIGS. 3 and4. A railway car is switched onto this track section and rolls along thesame until the leading axle thereof, indicated 115 in FIG. 4, strikesrollers 28 of the car holders. As the axle 115 strikes rollers 28, thecar holders are allowed to move to the right, as seen in FIGS. 2 and 4,in a cushioned manner by compression of springs 112 of cushion devices95. Springs 112 are of suflicient strength so that the car holders arereturned to almost the position they occupy when not engaged by railwaycars.

In the embodiment of the invention shown for purposes of illustration,springs 112 are compressed 3 inches when holding 12 average railwayfreight cars on a 2% grade. As subsequent cars are coupled to therailway car having axle 115 engaged by rollers 28, the car holders giveor roll to the right (as seen in the drawings) compressing the springs112 and absorbing or cushioning the coupling shocks transferred to thecar holders. Of course the railway car holder assembly also cushions thecoupling shocks when received when a switch engine or the like iscoupled with the cars being held by the car holders.

As noted in FIGS. 1 and 3, a plurality of vertically ex tending rails118 are embedded in footing 99, which rails have flanges abutting a sideedge of plate 98. These rails support the fixed parts of the cushioningdevices against longitudinal movement thereby reducing the shearstresses developed in the anchor bolts during operation of thecushioning devices.

It will be apparent from FIG. 4 that the car holders permit movement ofa railway car from right to left as seen in this figure. The axles ofthe car engage rollers 28 and thereby swing arms 25 in acounterclockwise directionto allow passage of the car. As soon as a railaxle passes rollers 28, arms 25 are immediately erected or returned tothe vertical position by means of springs 37. Accordingly, when arailway car which has just passed the car holders from right to left asseen in FIG. 4, returns down the graded track, the arms of the carholders will be in a position to engage the axle for holding the car onthe graded track section. Subsequent cars may then be coupled to thiscar from either direction. As noted in FIG. 4, the height of arms 25 issuch that the center line of rollers 28 is slightly above the centerline of rail axle 115. This constructional feature prevents axle 115from jumping over rollers 28 when the axle engages the rollers fromright to left as seen in FIG. 4.

When it is not desired to use the railway car holder assembly of thisinvention, arms 25 of the car holders are collapsed and held in theircollapsed position by means of foot operated plates 67. Arms 25 may bequickly and easily erected by depressing plates 67 by a persons foot.

It should be apparent that by reason of the cushioning devices connectedwith the car holders for cushioning movement of the latter, substantialcoupling shocks may be received by the car holders without damaging thelatter or the railway car truck assembly having the axle thereof engagedby the car holders. It should be noted that as rollers 28 engage therailway car axle, e.g. axle 115, at two places near respective ends ofthe latter, the bending movements in the axle are kept to a minimum.Further, as rollers 28 of the car holders engage the axle at two placesequidistantly spaced from the car center line, there is no tendency ofthe car holders to cock or rotate the railway car truck assembly andderail the latter. Further, it should be noted that as the car holdersare pivotally secured to cross link or equalizer bar which is pivotallysecured at its midpoint to the cushioning device, equal loads are takenby both car holders in arresting movement of a railway car.

During reciprocal movement of the car holders in the trackways definedby channels 74 and 75, magnets 51, 56 carried by the car holders act toclear metallic debris from the trackways thereby minimizing thepossibility of jamming or sticking of the car holders in respectivetrackways.

While the invention has been shown but in one form, it
